Method Detail

appendConstant

public StringConcatenator appendConstant(String value)

Registers the given constant string, which will be added on finish().

Returns:

this

appendVariable

public StringConcatenator appendVariable(org.objectweb.asm.tree.InsnList insns,
                                         org.objectweb.asm.Type type)

Registers the given code fragment, which will be executed, and the result added on finish().

Parameters:

insns - Instructions which must produce exactly one value of type on the operand stack

Returns:

this

appendVariablePrettily

public StringConcatenator appendVariablePrettily(org.objectweb.asm.tree.InsnList code,
                                                 org.objectweb.asm.Type type)

Registers the given code fragment, which will be executed, and the result added on finish(). If the type is an array, a string, StringBuffer, StringBuilder, CharSequence or a char, then it is 'pretty-printed' i nthe style of a Java constant.

Parameters:

code - Instructions which must produce exactly one value of type on the operand stack

Returns:

this

finish

public org.objectweb.asm.tree.InsnList finish()

Returns:

The InsnList that implements the creation of the string result
