## net.sf.saxon.trans
Class CompilerInfo

    java.lang.Object
      net.sf.saxon.trans.CompilerInfo

All Implemented Interfaces:
  Serializable

    public class CompilerInfo

extends Object
implements Serializable

This class exists to hold information associated with a specific XSLT compilation episode. In JAXP, the URIResolver and ErrorListener used during XSLT compilation are those defined in the TransformerFactory. The .NET API and the s9api API, however, allow finer granularity, and this class exists to support that.

  Since:
    9.2

### setCompileWithTracing

    public void setCompileWithTracing(boolean trueOrFalse)

  Set whether trace hooks are to be included in the compiled code. To use tracing, it is necessary both to compile the code with trace hooks included, and to supply a TraceListener at run-time

  Parameters:
    `trueOrFalse` - true if trace code is to be compiled in, false otherwise
  Since:
    8.9

### isCompileWithTracing

    public boolean isCompileWithTracing()

    true if trace hooks are included, false if not.
  Since:
    8.9

### setRecoveryPolicy

    public void setRecoveryPolicy(int policy)

  Set the policy for handling recoverable errrors. Note that for some errors the decision can be made at run-time, but for the "ambiguous template match" error, the decision is (since 9.2) fixed at compile time.

  Parameters:
    `policy` - the recovery policy to be used. The options are `Configuration.RECOVER_SILENTLY`, `Configuration.RECOVER_WITH_WARNINGS`, or `Configuration.DO_NOT_RECOVER`.
  Since:
    9.2

### getRecoveryPolicy

    public int getRecoveryPolicy()

  Returns:
    the current policy.
  Since:
    9.2

### isVersionWarning

    public boolean isVersionWarning()

  Ask whether a warning is to be output when the stylesheet version does not match the processor version. In the case of stylesheet version="1.0", the XSLT specification requires such a warning unless the user disables it.

  Returns:
    true if these messages are to be output.
  Since:
    9.2

### setVersionWarning

    public void setVersionWarning(boolean warn)

  Say whether a warning is to be output when the stylesheet version does not match the processor version. In the case of stylesheet version="1.0", the XSLT specification requires such a warning unless the user disables it.

  Parameters:
    `warn` - true if these messages are to be output.
  Since:
    9.2

### setSchemaAware

    public void setSchemaAware(boolean schemaAware)

  Say that the stylesheet must be compiled to be schema-aware, even if it contains no xsl:import-schema declarations. Normally a stylesheet is treated as schema-aware only if it contains one or more xsl:import-schema declarations. If it is not schema-aware, then all input documents must be untyped, and validation of temporary trees is disallowed (though validation of the final result tree is permitted). Setting the argument to true means that schema-aware code will be compiled regardless.

  Parameters:
    `schemaAware` - If true, the stylesheet will be compiled with schema-awareness enabled even if it contains no xsl:import-schema declarations. If false, the stylesheet is treated as schema-aware only if it contains one or more xsl:import-schema declarations
  Since:
    9.2

### isSchemaAware

    public boolean isSchemaAware()

  Ask whether schema-awareness has been requested by means of a call on `setSchemaAware(boolean)`

  Returns:
    true if schema-awareness has been requested

### setDefaultInitialTemplate

    public void setDefaultInitialTemplate(StructuredQName initialTemplate)

  Set the default initial template name for a stylesheet compiled using this CompilerInfo. This is only a default; it can be overridden when the stylesheet is executed

  Parameters:
    `initialTemplate` - the name of the default initial template, or null if there is no default. No error occurs (until run-time) if the stylesheet does not contain a template with this name.
  Since:
    9.3

### getDefaultInitialTemplate

    public StructuredQName getDefaultInitialTemplate()

  Get the default initial template name for a stylesheet compiled using this CompilerInfo. This is only a default; it can be overridden when the stylesheet is executed

  Returns:
    the name of the default initial template, or null if there is no default, as set using `setDefaultInitialTemplate(net.sf.saxon.om.StructuredQName)`
  Since:
    9.3

### setDefaultInitialMode

    public void setDefaultInitialMode(StructuredQName initialMode)

  Set the default initial mode name for a stylesheet compiled using this CompilerInfo. This is only a default; it can be overridden when the stylesheet is executed

  Parameters:
    `initialMode` - the name of the default initial mode, or null if there is no default. No error occurs (until run-time) if the stylesheet does not contain a mode with this name.
  Since:
    9.3

### getDefaultInitialMode

    public StructuredQName getDefaultInitialMode()

  Get the default initial mode name for a stylesheet compiled using this CompilerInfo. This is only a default; it can be overridden when the stylesheet is executed

  Returns:
    the name of the default initial mode, or null if there is no default, as set using `setDefaultInitialMode(net.sf.saxon.om.StructuredQName)`
  Since:
    9.3

### setXsltVersion

    public void setXsltVersion(DecimalValue version)

  Set the version of XSLT to be supported by this processor. This determines the version of the XSLT specification to which the processor conforms. This does not have to match the version attribute in the stylesheet; for example if the processor version is 2.0 and the stylesheet is version 3.0, then the stylesheet will be processed using the rules for a 2.0 processor in forwards compatibility mode, rather than the rules for a 3.01 processor.

  The value 0.0 (which is the default) indicates that the processor version is to be taken from the version attribute of the xsl:stylesheet element.

  XSLT 2.1 features are supported only in Saxon-EE. Setting the version to 3.0 here will not fail if the wrong edition is in use, but use of XSLT 3.0 features will fail subsequently.

  Parameters:
    `version` - must be numerically equal to 0.0, 2.0 or 3.0
  Throws:
    `IllegalArgumentException` - if the version is invalid
  Since:
    9.3

### getXsltVersion

    public DecimalValue getXsltVersion()

  Get the version of XSLT supported by this processor

  Returns:
    `DecimalValue.TWO` or `DecimalValue.THREE`, or zero indicating that the processor versino is taken from the version attribute of the xsl:stylesheet element.)
  Since:
    9.3
