2.4 Some Field-Map scripting key terms

field

Although a field in a database is an intersection between one row (record) and one column (attribute), Field-Map Object Pascal uses the identifier "field" only to refer to the column, i.e. the name of the attribute, e.g. Trees['DBH_mm']. In the previous example the record is not specified: the active record is automatically referred to.

Some Field-Map functions also use parameters of names such as "field" or "keyField", which specify the desired attribute. This reference often means that all records in the table will be iterated through (e.g. to locate a specific value in a specified table - see the Locate function, or to find the minimum value - see the GetMinOfAttributeValues function, etc.).

members

Members refer to functions, procedures and properties of classes used in Field-Map scripting. For example, the LayerCount property is a member of the TFieldMapProjectWrapperClass.
