Initializes a new instance of the ISOLatin1AccentFilter class

The caller must pass in a Class<? extends Attribute> value. This method first checks if an instance of that class is already in this AttributeSource and returns it. Otherwise a new instance is created, added to this AttributeSource and returned. Signature for Java 1.5:

CopyC#

public <T extends Attribute> T addAttribute(Class<T>)

Adds a custom AttributeImpl instance with one or more Attribute interfaces.

Captures the state of all Attributes. The return value can be passed to {@link #restoreState} to restore the state of this or another AttributeSource.

Resets all Attributes in this AttributeSource by calling {@link AttributeImpl#Clear()} on each Attribute implementation.

Performs a clone of all {@link AttributeImpl} instances returned in a new AttributeSource instance. This method can be used to e.g. create another TokenStream with exactly the same attributes (using {@link #AttributeSource(AttributeSource)})

Close the input TokenStream.

Performs end-of-stream operations, if any, and calls then

CopyC#

end()

on the input TokenStream.

NOTE: Be sure to call

first when overriding this method.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

The caller must pass in a Class<? extends Attribute> value. Returns the instance of the passed in Attribute contained in this AttributeSource Signature for Java 1.5:

CopyC#

public <T extends Attribute> T getAttribute(Class<T>)

Returns a new iterator that iterates the attribute classes in the same order they were added in. Signature for Java 1.5:

CopyC#

public Iterator<Class<? extends Attribute>> getAttributeClassesIterator()

Note that this return value is different from Java in that it enumerates over the values and not the keys

returns the used AttributeFactory.

Returns a new iterator that iterates all unique Attribute implementations. This iterator may contain less entries that {@link #getAttributeClassesIterator}, if one instance implements more than one Attribute interface. Signature for Java 1.5:

CopyC#

public Iterator<AttributeImpl> getAttributeImplsIterator()

Gets the Type of the current instance.

The caller must pass in a Class<? extends Attribute> value. Returns true, iff this AttributeSource contains the passed-in Attribute. Signature for Java 1.5:

CopyC#

public boolean hasAttribute(Class<? extends Attribute>)

Returns true, iff this AttributeSource has any attributes

Creates a shallow copy of the current Object.

To replace accented characters in a String by unaccented equivalents.

Reset the filter as well as the input TokenStream.

Restores this state by copying the values of all attribute implementations that this state contains into the attributes implementations of the targetStream. The targetStream must contain a corresponding instance for each argument contained in this state (e.g. it is not possible to restore the state of an AttributeSource containing a TermAttribute into a AttributeSource using a Token instance as implementation). Note that this method does not affect attributes of the targetStream that are not contained in this state. In other words, if for example the targetStream contains an OffsetAttribute, but this state doesn't, then the value of the OffsetAttribute remains unchanged. It might be desirable to reset its value to the default, in which case the caller should first call {@link TokenStream#ClearAttributes()} on the targetStream.
