Examples of ConstantExpression

com.facebook.presto.sql.relational.ConstantExpression
com.foundationdb.sql.optimizer.plan.ConstantExpression
An operand with a constant value.
com.ocpsoft.pretty.faces.el.ConstantExpression
Implementation of {@link PrettyExpression} used when the EL expression isknown in advance. @author Christian Kaltepoth
edu.uci.ics.hyracks.algebricks.core.algebra.expressions.ConstantExpression
oracle.toplink.essentials.internal.expressions.ConstantExpression
Used for wrapping constant values.
org.apache.camel.model.language.ConstantExpression
For expressions and predicates using a constant
org.apache.commons.betwixt.expression.ConstantExpression

ConstantExpression represents a constant expression.

In other words, {@link #evaluate} returns a value independent of the context.

org.eclipse.persistence.internal.expressions.ConstantExpression
Used for wrapping constant values.
org.geotools.filter.ConstantExpression
The Expression class is not immutable!
However we do have a need for immutable literal expressions when defining our API for SLD, and any other standards based on Expression.
