                 throws java.io.IOException

Skip to the correct level of the stack (going down into the stack).

Parameters:

reader - Reader representing the stack trace.

readBytes

protected byte[] readBytes(java.lang.Throwable detail)
                    throws java.io.IOException

Read a throwable stack trace as an array of bytes.

Parameters:

detail - Throwable to get trace from.

Returns:

Throwable stack trace as an array of bytes.

Throws:

java.io.IOException

createReader

protected java.io.BufferedReader createReader(java.lang.Throwable detail)
                                       throws java.io.IOException

Create a reader for the trace of the given Throwable.

Parameters:

detail - Thorwable to get trace from.

Returns:

Reader for the throwable stack trace.

Throws:

java.io.IOException

parse

public java.util.List parse(java.lang.Throwable detail,
                            int level,
                            int limit)

Parse a Throwable stack trace.

Parameters:

detail - Throwable to get trace from.

level - Number of levels down to begin parsing.

limit - The maximum number of entries to parse (does not include skipped levels or the description). A value <= zero results in all entries being parsed.

Returns:

getInstance

public static final StackTrace.Parser (src)  getInstance()
                                           throws java.lang.InstantiationException

Get the stack trace parser for this virtual machine.

Returns:

Stack trace parser

Throws:
