Package guru.mikelue.foxglove.functional

package guru.mikelue.foxglove.functional

Provides utilities for functional interfaces.

Interfaces for DataSetting

• ColumnMatcher - Used to match a column by its metadata.
• SupplierDecider - A Function turns a ColumnMeta to a Supplier.

Featured Suppliers

• Int4SequenceSupplier, Int8SequenceSupplier - Used to generate sequence numbers for integer types.
• RoundRobinValueSupplier provides round robin behavior over a domain of values
• RowIndexToValue defines the Function which converts an index of row(generated for a table facet) to certain value

Supplier wrapper

Suppliers provides utilities to wrap a Supplier with extra behavior.

• Suppliers.rollingSupplier(Supplier) makes Supplier.get() emitting null value with customizable odds
• Suppliers.lazySupplier(Supplier) makes the instantiation of a Supplier to be delayed until the first time calling of Supplier.get().
