    public abstract class ValueCompiler

extends Object

Compile a literal value to Java code

Constructor Summary
`ValueCompiler()`

Method Summary
`void` | `compilePush(CompilerService compiler, Value value)`
`String` | `compileToCharSequence(CompilerService compiler, AtomicValue av)` Compile Java code whose effect is to compute the string value of the expression; the generated code returns a CharSequence.
`String` | `compileToEffectiveBooleanValue(CompilerService compiler, Value expr, ReturnAction options)`
`String` | `compileToItem(CompilerService compiler, AtomicValue value)`
`String` | `compileToIterator(CompilerService compiler, Value val)`
`Class` | `getJavaClass(AtomicValue value)`
`abstract String` | `toJavaExpression(AtomicValue value, CompilerService compiler)`

Method Detail

### compilePush

    public void compilePush(CompilerService compiler,
                            Value value)

### compileToItem

    public String compileToItem(CompilerService compiler,
                                AtomicValue value)

### compileToIterator

    public String compileToIterator(CompilerService compiler,
                                    Value val)

### compileToEffectiveBooleanValue

    public String compileToEffectiveBooleanValue(CompilerService compiler,
                                                 Value expr,
                                                 ReturnAction options)

### compileToCharSequence

    public String compileToCharSequence(CompilerService compiler,
                                        AtomicValue av)

  Compile Java code whose effect is to compute the string value of the expression; the generated code returns a CharSequence. This method must only be called for an expression that is known to return a value of type xs:string

  Parameters:
    `av` - The atomic value to be compiled
  Returns:
    the name of a variable to which the resulting CharSequence is assigned, or a Java expression that can be used in a place where a variable reference of type CharSequence is allowed.

### toJavaExpression

    public abstract String toJavaExpression(AtomicValue value,
                                            CompilerService compiler)

### getJavaClass

    public Class getJavaClass(AtomicValue value)
