LocatorImpl

public class LocatorImpl
extends Object implements Locator

java.lang.Object
↳	org.xml.sax.helpers.LocatorImpl

Known Direct Subclasses

Locator2Impl

Provide an optional convenience implementation of Locator.

This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. See http://www.saxproject.org for further information.

This class is available mainly for application writers, who can use it to make a persistent snapshot of a locator at any point during a document parse:

 Locator locator;
 Locator startloc;

 public void setLocator (Locator locator)
 {
         // note the locator
   this.locator = locator;
 }

 public void startDocument ()
 {
         // save the location of the start of the document
         // for future use.
   Locator startloc = new LocatorImpl(locator);
 }

Normally, parser writers will not use this class, since it is more efficient to provide location information only when requested, rather than constantly updating a Locator object.

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

LocatorImpl

Added in API level 1

LocatorImpl ()

Zero-argument constructor.

This will not normally be useful, since the main purpose of this class is to make a snapshot of an existing Locator.

LocatorImpl

Added in API level 1

LocatorImpl (Locator locator)

Copy constructor.

Create a persistent copy of the current state of a locator. When the original locator changes, this copy will still keep the original values (and it can be used outside the scope of DocumentHandler methods).

Parameters
`locator`	`Locator`: The locator to copy.

Public methods

getColumnNumber

Added in API level 1

int getColumnNumber ()

Return the saved column number (1-based).

Returns
`int`	The column number as an integer, or -1 if none is available.

See also:

getLineNumber

Added in API level 1

int getLineNumber ()

Return the saved line number (1-based).

Returns
`int`	The line number as an integer, or -1 if none is available.

See also:

getPublicId

Added in API level 1

String getPublicId ()

Return the saved public identifier.

Returns
`String`	The public identifier as a string, or null if none is available.

See also:

getSystemId

Added in API level 1

String getSystemId ()

Return the saved system identifier.

Returns
`String`	The system identifier as a string, or null if none is available.

See also:

setColumnNumber

Added in API level 1

void setColumnNumber (int columnNumber)

Set the column number for this locator (1-based).

Parameters
`columnNumber`	`int`: The column number, or -1 if none is available.

See also:

getColumnNumber()

setLineNumber

Added in API level 1

void setLineNumber (int lineNumber)

Set the line number for this locator (1-based).

Parameters
`lineNumber`	`int`: The line number, or -1 if none is available.

See also:

getLineNumber()

setPublicId

Added in API level 1

void setPublicId (String publicId)

Set the public identifier for this locator.

Parameters
`publicId`	`String`: The new public identifier, or null if none is available.

See also:

getPublicId()

setSystemId

Added in API level 1

void setSystemId (String systemId)

Set the system identifier for this locator.

Parameters
