Imports
io.github.spannm.jackcess.impl.ColumnImpl, io.github.spannm.jackcess.impl.expr.Expressionator, java.io.IOException, .UncheckedIOException, java.util.function.Predicate, java.util.regex.Pattern
Predicate which tests a column value against a Pattern. The static factory methods can be used to construct the Pattern from various forms of wildcard pattern syntaxes.

This class can be used as a value pattern in the various Cursor search methods, e.g. io.github.spannm.jackcess.Cursor#findFirstRow(io.github.spannm.jackcess.Column, Object).
