Detailed Description

Java wrapper for the Qore::AbstractIterator class in Qore.

Note

Loads and initializes the Qore library and the jni module in static initialization if necessary

Member Function Documentation

getValue()

Object org.qore.lang.AbstractIterator.getValue ( ) throws Throwable

inline

returns the current value

Returns

the current value

Exceptions

INVALID-ITERATOR

the iterator is not pointing at a valid element

See also

AbstractIterator::valid()

Reimplemented in org.qore.lang.dataprovider.AbstractDataProviderBulkRecordInterface, and org.qore.lang.dataprovider.AbstractDataProviderRecordIterator.

next()

boolean org.qore.lang.AbstractIterator.next ( ) throws Throwable

inline

Moves the current position to the next element; returns False if there are no more elements.

This method will return True again after it returns False once if the object being iterated is not empty, otherwise it will always return False. The iterator object should not be used after this method returns False

Returns

False if there are no more elements (in which case the iterator object is invalid and should not be used); True if successful (meaning that the iterator object is valid)

valid()

boolean org.qore.lang.AbstractIterator.valid ( ) throws Throwable

inline

returns true if the iterator is currently pointing at a valid element, false if not

Returns

true if the iterator is currently pointing at a valid element, false if not

Reimplemented in org.qore.lang.dataprovider.AbstractDataProviderBulkRecordInterface.
