Constructor Detail

ExpressionTableColumnModel

public ExpressionTableColumnModel(String[] arrColumnInfo,
                                  boolean bSorted,
                                  ExpressionEvaluator expressionEvaluator)

Constructs a table column model containting OGNL expression columns.
The data for the columns is provided in the form of a string array, where the info of each column is stored in two consecutive fields in the array, hence its size must be even. The expected info is the following:

• Column Name
• OGNL expression

Parameters:

arrColumnInfo - The information to construct the columns from

bSorted - Whether all columns are sorted or not

ExpressionTableColumnModel

public ExpressionTableColumnModel(Object[] arrColumnInfo,
                                  ExpressionEvaluator expressionEvaluator)

Constructs a table column model containting OGNL expression columns.
The data for the columns is provided in the form of a string array, where the info of each column is stored in four consecutive fields in the array, hence its size must be divisible by 4.
The expected info is the following:

• Column Name
• Display Name
• OGNL expression
• Sorting of the column. This is either a Boolean, or a String representation of a boolean.

Parameters:

arrColumnInfo -
