Method Detail

getVariableHandle

public int getVariableHandle(java.lang.String var,
                             boolean begin)

Description copied from class: Regex

Returns variable index handle that can be used later to get or set variable value efficiently. If efficiency is not a concern, use get and set methods instead. Every variable has two index handles - 'begin' and 'end' index handle.

Overrides:

getVariableHandle in class Regex

getExtVariableHandle

public int getExtVariableHandle(java.lang.String var)

Description copied from class: Regex

Returns external variable buffer handle that can be used later to get or set variable value efficiently. If efficiency is not a concern, use get and set methods instead. Only external variables have buffer handle. This is different from index handles. For internal variables this method returs -1.

Overrides:

getExtVariableHandle in class Regex

variables

public java.util.Enumeration variables()

Description copied from class: Regex

Enumerates all external and internal variables in this regex.

Overrides:

variables in class Regex

init

public void init(char[] arr,
                 int off,
                 int len)

Description copied from class: Regex

Prepares to match or search. Sets up an input buffer and a range of characters in it that is to be searched or matched.

Overrides:

init in class Regex

searchAgain

public boolean searchAgain()

Description copied from class: Regex

Search the buffer (that was set up by init method) for a substring that matches this regex. See description of this class for difference between search and match. On success do not discard record of all other possible matches, so if this method is called again, different way of matching can be found for already found substring or a substring overlapping already found substring. Most often, search(), not searchAgain() should be used.

Overrides:

searchAgain in class Regex

search

public boolean search()

Description copied from class: Regex

Search the buffer (that was set up by init method) for a substring that matches this regex. See description of this class for difference between search and match. All records for other possible matches withing matching substring that was found are destroyed, so if this method is called again, search will start at the first position after previously found substring.

Overrides:

search in class Regex

match

public boolean match()

Description copied from class: Regex

Match the beginning of the buffer (that was set up by init method) against this regex. See description of this class for difference between search/match/matchWhole.

Overrides:

match in class Regex

matchWhole

public boolean matchWhole()

Description copied from class: Regex

Match the buffer (that was set up by init method) against this regex. See description of this class for difference between search/match/matchWhole.

Overrides:

matchWhole in class Regex

getIndex

public int getIndex(int handle)

Description copied from class: Regex

Returns external or internal variable index using its index handle. Every variable has two indices - 'begin' and 'end'. Use 'begin' and 'end' handles to get them. These indices can be used to determine which part of the input buffer (set by init method) corresponding internal variable matched. An external variable 'begin' and 'end' indices point to its own buffer. They are assinged by setIndex and are never changed.

Overrides:

getIndex in class Regex

setIndex

public void setIndex(int handle,
                     int value)

Description copied from class: Regex

Returns internal variable index using its index handle. Every variable has two indices - 'begin' and 'end'. Use 'begin' and 'end' handles to assign them. These indices are needed to completely specify value of an external variable.

Overrides:

setIndex in class Regex

getCharBuffer

public char[] getCharBuffer(int extHandle)

Description copied from class: Regex

Returns external variable buffer by its buffer handle. If -1 is passed as a handle the input buffer that was set up for matching (using init) is returned.

Overrides:

getCharBuffer in class Regex

getMatchStart

public int getMatchStart()

Description copied from class: Regex

After successiful search returns matching substring's initial position in the input buffer (that was set up by init method).

Overrides:

getMatchStart in class Regex

getMatchEnd

public int getMatchEnd()

Description copied from class: Regex

After successiful search returns matching substring's final position in the input buffer (that was set up by init method).

Overrides:

getMatchEnd in class Regex

setExtVariableBuffer

public void setExtVariableBuffer(int extHandle,
                                 char[] arr)

Description copied from class: Regex

Assignes external variable buffer by its buffer handle. It is needed to completely specify value of an external variable.

Overrides:

setExtVariableBuffer in class Regex

setRefiller

public void setRefiller(RegexRefiller refiller)

Overrides:

setRefiller in class Regex

setRefilledBuffer

public void setRefilledBuffer(char[] buffer)

Description copied from class: Regex

Refiller can call this method after refilling the buffer, if buffer has been reallocated.

Overrides:

setRefilledBuffer in class Regex

cloneRegex

public Regex cloneRegex()

Overrides:

cloneRegex in class Regex

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
