The IParametersMap interface represent a collection of name-value pairs. The name is a string and the value is of type IValue. These source code parameters are usually defined in square brackets like this:
[name="Kevin", age=27, hacker=true]
The main methods defined on parameter maps are exists(), getValue(), getSourceRange() and getParameterNames(). In addition there are some convenience methods for easy retrieval of values of specific types:

| Method | Description |
|---|---|
| boolean exist(String paramName) | Tells if a parameter of the given name exists. |
| boolean getBoolValue(String paramName, boolean defaultValue) | Returns the boolean parameter of the given name. The default is returned in case of an undefined value. |
| <T extends Enum<?>> T getEnumValue(Class<T> enumeration, String name, T defaultLitteral) | Returns the enum parameter of the given name. The default is returned in case of an undefined value. |
| int getIntValue(String paramName, int defaultValue) | Returns the int parameter of the given name. The default is returned in case of an undefined value. |
| Collection<String> getParameterNames() | Returns the names of the defined parameters. |
| ISourceRange getSourceRange(String paramName) | Returns the position at which this parameter is defined in the source code. |
| String getStringValue(String paramName, String defaultValue) | Returns the string parameter of the given name. The default is returned in case of an undefined value. |
| IValue getValue(String paramName) | Returns the value of the parameter with the given name. |
