public Object readConst(final int item, final char[] buf)

Overrides org.objectweb.asm.ClassReader.readConst.

Doc from org.objectweb.asm.ClassReader.readConst.

Reads a numeric or string constant pool entry in this ClassReader. This method is intended for Attribute sub classes, and is normally not needed by class generators or adapters.

Parameters
item:int

the index of a CONSTANT_Integer, CONSTANT_Float, CONSTANT_Long, CONSTANT_Double, CONSTANT_Class, CONSTANT_String, CONSTANT_MethodType, CONSTANT_MethodHandle or CONSTANT_Dynamic entry in the class's constant pool.

buf:char[]

the buffer to be used to read strings. This buffer must be sufficiently large. It is not automatically resized.

Returns:Object

the Integer, Float, Long, Double, String, Type, Handle or ConstantDynamic corresponding to the specified constant pool entry.

public int readUnsignedShort(final int index)

Overrides org.objectweb.asm.ClassReader.readUnsignedShort.

Doc from org.objectweb.asm.ClassReader.readUnsignedShort.

Reads an unsigned short value in this ClassReader. This method is intended for Attribute sub classes, and is normally not needed by class generators or adapters.

Parameters
index:int

the start index of the value to be read in this ClassReader.

Returns:int

the read value.

public String readUTF8(final int arg0, final char[] arg1)

Overrides org.objectweb.asm.ClassReader.readUTF8.

Doc from org.objectweb.asm.ClassReader.readUTF8.

Reads a CONSTANT_Utf8 constant pool entry in this ClassReader. This method is intended for Attribute sub classes, and is normally not needed by class generators or adapters.

Parameters
arg0:int

the start offset of an unsigned short value in this ClassReader, whose value is the index of a CONSTANT_Utf8 entry in the class's constant pool table.

arg1:char[]

Returns:String

the String corresponding to the specified CONSTANT_Utf8 entry.
