Method Detail

getMemoryInKiloByte

public int getMemoryInKiloByte(double memoryValue,
                               char memUnit,
                               String line)

Returns the amount of memory in kilobyte. Depending on memUnit, input is converted to kilobyte.

Parameters:

memoryValue - amount of memory

memUnit - memory unit

line - line that is parsed

Returns:

amount of memory in kilobyte

parseType

public AbstractGCEvent.ExtendedType parseType(String typeString)
                                       throws UnknownGcTypeException

Returns the ExtendedType for typeString, if it can find one. If there is a type name including gc cause ("ParNew (promotion failed)", where (promotion failed) is the gc cause), the cause is removed while trying to find the type.

Parameters:

typeString - string representation of the gc event

Returns:

ExtendedType representing typeString

Throws:

UnknownGcTypeException - If typeString can't be converted to an ExtendedType

parseTypeWithCause

public AbstractGCEvent.ExtendedType parseTypeWithCause(String typeName)

Same as @{link parseType(String)}, but returns null instead of exception, if no type could be found.

Parameters:

typeName - string representation of the gc event

Returns:

ExtendedType representing typeString, or null if none could be found
