Constructor Detail

ValueBindingExpression

public ValueBindingExpression(String expression)

Creates an instance of a ValueBindingExpression based on a well formed EL expression.

Parameters:

expression - The EL expression

Method Detail

replaceOrAddProperty

public static ValueBindingExpression replaceOrAddProperty(ValueBindingExpression valueBindingExpression,
                                                          String newProperty)

The given property is used as new property of the expression. Examples for 'newProperty':
#{bean} -> #{bean.newProperty}

#{bean.property} -> #{bean.newProperty}

Parameters:

valueBindingExpression - The target instance of ValueBindingExpression

newProperty - The property to use.

Returns:

The resulting ValueBindingExpression (with the new property)

replaceProperty

public static ValueBindingExpression replaceProperty(ValueBindingExpression valueBindingExpression,
                                                     String newProperty)

Replace the property in the expression string with the given property.

Parameters:

valueBindingExpression - The valueBindingExpression where we want to replace the property

newProperty - The new property which should replace the existing one.

Returns:

The resulting ValueBindingExpression (with the new property)

addProperty

public static ValueBindingExpression addProperty(ValueBindingExpression valueBindingExpression,
                                                 String newProperty)

Adds the property to the given ValueBindingExpression.

Parameters:

valueBindingExpression - The valueBindingExpression where we want to add the property

newProperty - The property to add.

Returns:

The resulting ValueBindingExpression (with the new property)

getProperty

public String getProperty()

The (last) property of the expression.

Returns:

The (last) property of the expression.

getBaseExpression

public ValueBindingExpression getBaseExpression()

getExpressionString

public String getExpressionString()

Recreates the expression string from which this valueBindingExpression was build. There is no guarantee that the same format is kep, for example {#bean['property']} could become {#bean.property}

Returns:

The expression string equivalent of the valueBindingExpression.

getPrefix

public String getPrefix()

setPrefix

public void setPrefix(String prefix)

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object target)

Overrides:

equals in class Object
