List of reposition() Examples

Examples of reposition()

com.slytechs.utils.memory.BufferBlock.reposition()
com.slytechs.utils.memory.PartialBuffer.reposition()
Repositions the ByteBuffer properties "position" and "limit" to the bounds specified by regional and length. The regional position is remapped to a local posiiton and the buffer properites are reset. @param regional regional position to set the ByteBuffer "position" property @param length the length of the requested region which is also used to calculate the ByteBuffer's limit property value
edu.cornell.med.icb.goby.alignments.AlignmentReader.reposition()
edu.cornell.med.icb.goby.alignments.AlignmentReaderImpl.reposition()
edu.cornell.med.icb.goby.counts.CountBinningAdapterI.reposition()
edu.cornell.med.icb.goby.counts.CountBinningAdaptor.reposition()
org.apache.derby.impl.jdbc.PositionedStoreStream.reposition()
Repositions the underlying store stream to the requested position.
Repositioning is required because there can be several uses of the store stream, which changes the position of it. If a class is dependent on the underlying stream not changing its position, it must call reposition with the position it expects before using the stream again. @throws IOException if reading from the store stream fails @throws StandardException if resetting the store in stream fails, orsome other exception happens in store @see #getPosition
