Constructor Detail

TokensIterator

public TokensIterator(java.lang.String attributeName)

INTERNAL: Creates an instance of attribute name tokenizer iterator. Simple parser without prefix parsing will be used so ("key." and "value.") will be returned as regular attribute name tokens.

Parameters:

attributeName - Attribute name to be parsed.

TokensIterator

public TokensIterator(java.lang.String attributeName,
                      boolean isPrefix)

INTERNAL: Creates an instance of attribute name tokenizer iterator.

Parameters:

attributeName - Attribute name to be parsed.

isPrefix - Do search for attribute name prefixes ("key." and "value.")?

Method Detail

getPrefix

public AttributeNamePrefix getPrefix()

INTERNAL: Get attribute name prefix.

Returns:

Attribute name prefix.

hasNext

public boolean hasNext()

INTERNAL: Returns true if the iteration has more elements. In other words, returns true if next() would return an element rather than throwing an exception.

Specified by:

hasNext in interface java.util.Iterator<java.lang.String>

Returns:

Value of true if the iteration has more elements or false otherwise.

next

public java.lang.String next()
                      throws java.util.NoSuchElementException

INTERNAL: Return the next attribute name token from attribute name.

Specified by:

next in interface java.util.Iterator<java.lang.String>

Returns:

The next attribute name token.

Throws:

java.util.NoSuchElementException - when attribute name has no more tokens.

remove

public void remove()

INTERNAL: Removal of attribute name tokens makes no sense.

Specified by:

remove in interface java.util.Iterator<java.lang.String>

Throws:

java.lang.UnsupportedOperationException - is always thrown on invocation.
