Method Detail

compilePush

public void compilePush(CompilerService compiler,
                        Value value)

compileToItem

public java.lang.String compileToItem(CompilerService compiler,
                                      AtomicValue value)

compileToIterator

public java.lang.String compileToIterator(CompilerService compiler,
                                          Value val)

compileToEffectiveBooleanValue

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

compileToCharSequence

public java.lang.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 java.lang.String toJavaExpression(AtomicValue value,
                                                  CompilerService compiler)

getJavaClass

public java.lang.Class getJavaClass(AtomicValue value)
