Method Summary

static java.lang.Object	getProperty(java.lang.Object object, java.util.List expressionElements) Uses a PropertyAdapter to traverse the bean and meta-object properties specified by the pre-parsed list of expression elements.
static java.lang.Object	getProperty(java.lang.Object object, java.lang.String expression) Uses bean Introspection via org.progeeks.util.Inspector to access a sequence of nested properties specified by the spring expression.
static java.util.List	parseExpression(java.lang.String expression) Parses the expression and returns a list of elements found.
static void	setProperty(java.lang.Object object, java.util.List expressionElements, java.lang.Object value) Uses bean introspection via org.progeeks.util.Inspector to access a sequence of nested properties specified by the string expression and set the last property in the chain.
static void	setProperty(java.lang.Object object, java.lang.String expression, java.lang.Object value) Uses bean introspection via org.progeeks.util.Inspector to access a sequence of nested properties specified by the string expression and set the last property in the chain.

Method Detail

parseExpression

public static java.util.List parseExpression(java.lang.String expression)

Parses the expression and returns a list of elements found. Otherwise, throws a RuntimeException. This simply delegates to the PropertyUtils version.

getProperty

public static java.lang.Object getProperty(java.lang.Object object,
                                           java.util.List expressionElements)

Uses a PropertyAdapter to traverse the bean and meta-object properties specified by the pre-parsed list of expression elements. Returns the single value at the end of the chain. If the chain ends early then null is returned.

getProperty

public static java.lang.Object getProperty(java.lang.Object object,
                                           java.lang.String expression)

Uses bean Introspection via org.progeeks.util.Inspector to access a sequence of nested properties specified by the spring expression. Returns the single value at the end of the chain. If the chain ends early then null is returned.

setProperty

public static void setProperty(java.lang.Object object,
                               java.lang.String expression,
                               java.lang.Object value)

Uses bean introspection via org.progeeks.util.Inspector to access a sequence of nested properties specified by the string expression and set the last property in the chain.

setProperty

public static void setProperty(java.lang.Object object,
                               java.util.List expressionElements,
                               java.lang.Object value)

Uses bean introspection via org.progeeks.util.Inspector to access a sequence of nested properties specified by the string expression and set the last property in the chain.
