Method Details

binary

public byte[] binary(InputInfo ii)
              throws QueryException

Returns the binary content.

Parameters:

ii - input info

Returns:

content

Throws:

QueryException - query exception

input

public BufferInput input(InputInfo ii)
                  throws QueryException

Description copied from class: Item

Returns an input stream.

Overrides:

input in class Item

Parameters:

ii - input info (can be null)

Returns:

input stream

Throws:

QueryException - query exception

toJava

public final byte[] toJava()
                    throws QueryException

Description copied from class: Value

Returns a Java representation of the value.

Specified by:

toJava in class Value

Returns:

Java object

Throws:

QueryException - query exception

equals

public boolean equals(Object obj)

Description copied from class: Expr

This function is e.g. called by:

• If.optimize(CompileContext), Switch.optimize(CompileContext), Typeswitch.optimize(CompileContext), in order to discard identical expressions.
• CmpR.mergeEbv(Expr, boolean, CompileContext) or CmpSR.mergeEbv(Expr, boolean, CompileContext), in order to merge expressions with identical input.
• CmpG.optimize(CompileContext) or CmpV.optimize(CompileContext), in order to pre-evaluate equality tests.
• CmpG.optimize(CompileContext) or Pos.get(Expr, CmpV.OpV, InputInfo, CompileContext), in order to compare the start and end value.
• PathCache, in order to find identical root values at runtime.

Specified by:

equals in class Expr
