Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Creates and returns a copy of this object. The constant pool object is shared between this object and the cloned object.

Throws:

java.lang.CloneNotSupportedException

size

public int size()

Returns exception_table_length, which is the number of entries in the exception_table[].

startPc

public int startPc(int nth)

Returns startPc of the n-th entry.

Parameters:

nth - the n-th (>= 0).

setStartPc

public void setStartPc(int nth,
                       int value)

Sets startPc of the n-th entry.

Parameters:

nth - the n-th (>= 0).

value - new value.

endPc

public int endPc(int nth)

Returns endPc of the n-th entry.

Parameters:

nth - the n-th (>= 0).

setEndPc

public void setEndPc(int nth,
                     int value)

value - new value.

handlerPc

public int handlerPc(int nth)

Returns handlerPc of the n-th entry.

Parameters:

nth - the n-th (>= 0).

setHandlerPc

public void setHandlerPc(int nth,
                         int value)

Sets handlerPc of the n-th entry.

Parameters:

nth - the n-th (>= 0).

value - new value.

catchType

public int catchType(int nth)

Returns catchType of the n-th entry.

Parameters:

nth - the n-th (>= 0).

Returns:

an index into the constant_pool table, or zero if this exception handler is for all exceptions.
