Class Summary

Class	Description
AbstractDataField
AbstractDataIntField
AbstractDataObjField
ArrayListAttachmentStrategy<T,C>
ByteArrayField	The ByteArrayField represents a linear byte array field with plain serialized form.
CompactCharField	The CompactCharField represents a single character field with UTF-8 serialized form.
CompactIntField	The CompactIntField represents an integer field with compact serialized form.
CompositeFilters	SubscriptionFilter utilities that combine other filters with ',' (or) operations, '&' (and) operations, and '!' (not) operations.
DateField
DecimalField	The DecimalField represents a decimal field with compact serialized form.
DefaultRecord	The DefaultRecord is a basic implementation of data record.
DefaultScheme	The DefaultScheme is a basic implementation of data scheme.
HashFilter	Symbol filter of form hashMofN that accepts symbols that belong to the specified hash group M out of N (where M and N are integers and M<N and N is a power of 2).
HashStriper	Strategy that splits symbol universe into stripes by hash groups.
LongField	The LongField represents a long integer field with compact serialized form.
MarshalledObjField	The MarshalledObjField represents an object field with plain Java serialized form.
MonoStriper	Identity symbol striper that does no splitting.
NotFilter	Default implementation for QDFilter.negate() operation.
PatternFilter	SubscriptionFilter that understands a simple GLOB-like grammar to specify matching symbols.
PentaCodec	The PentaCodec performs symbol coding and serialization using extensible 5-bit encoding.
PlainIntField	The PlainIntField represents an integer field with plain serialized form.
PlainObjField	Deprecated Use ByteArrayField with custom serialization whenever possible, or use MarshalledObjField that prevents unnecessary costly deserialization of objects in multiplexor nodes.
RangeFilter	Range symbol filter with specification range-<A>-<B>-, where A and B are range boundaries using dictionary [a-zA-Z0-9], accepts symbols that are greater or equal than A and less than B skipping non-dictionary prefix.
RangeStriper	Strategy that splits symbol universe into stripes by range boundaries.
RangeUtil	Utility class to strip symbols' prefixes for RangeStriper and RangeFilter.
RecordOnlyFilter	Subscription filter that filters only based on the record name.
SequenceField
ShortStringField	The ShortStringField represents a short (up to 4 characters) string in a single integer with compact serialized form.
StringField	The StringField represents a character sequence field with CESU-8 serialized form.
SymbolSetFilter	Fast filter based on SymbolSet.
SymbolStriperFactoryImpl
TimeField	Deprecated Use TimeSecondsField instead.
TimeMillisField
TimeSecondsField
VoidIntField
VoidObjField
WideDecimalField	The WideDecimalField represents a decimal field with compact serialized form.

Exception Summary

Exception	Description
FilterSyntaxException	Thrown to indicate that the specification for a filter or striper has syntax errors.
