Method Detail

getDataProvider

public DataProvider getDataProvider(String fieldName,
                                    int idx)

Description copied from class: ReflectiveDataProvider

Get the data provider from the reflected delegate. If a method based on the given fieldName can be reflected, this will return the result of calling that method. NOTE: if fieldName contains period ('.') characters, then this is considered to indicate a nested structure. This method will recursively descend through the reflected delegate attempting to obtain data. If a method along the way returns null, then reflection cannot delve any deeper and null will be returned.

Specified by:

getDataProvider in interface DataProvider

Specified by:

getDataProvider in class ReflectiveDataProvider

Returns:

the reflected value or null.

getDataProviderCount

public int getDataProviderCount(String fieldName)

Description copied from class: ReflectiveDataProvider

Get the data provider count from the reflected delegate. If a method based on the given fieldName can be reflected, this will return the result of calling that method. NOTE: if fieldName contains period ('.') characters, then this is considered to indicate a nested structure. This method will recursively descend through the reflected delegate attempting to obtain data. If a method along the way returns null, then reflection cannot delve any deeper and 0 will be returned.

Specified by:

getDataProviderCount in interface DataProvider

Specified by:

getDataProviderCount in class ReflectiveDataProvider

Returns:

the reflected value or 0.

hasDataProviderKey

public boolean hasDataProviderKey(String fieldName)

Description copied from class: ReflectiveDataProvider

Determine if the data provider key has been set. If a method based on the given fieldName can be reflected, this will return true, otherwise false. NOTE: if fieldName contains period ('.') characters, then this is considered to indicate a nested structure. This method will recursively descend through the reflected delegate attempting to answer the question. If a method along the way returns null, then reflection cannot delve any deeper and false will be returned.

Specified by:

hasDataProviderKey in interface DataProvider

Specified by:

hasDataProviderKey in class ReflectiveDataProvider

Parameters:

fieldName - the name of the field to use for reflection

Returns:

true if a method can be reflected to return a value.

getBoolean

public boolean getBoolean(String fieldName)

Description copied from class: ReflectiveDataProvider

Get the boolean value from the reflected delegate. If a method based on the given fieldName can be reflected, this will return the result of calling that method. NOTE: if fieldName contains period ('.') characters, then this is considered to indicate a nested structure. This method will recursively descend through the reflected delegate attempting to obtain data. If a method along the way returns null, then reflection cannot delve any deeper and false will be returned.

Specified by:

getBoolean in interface DataProvider

Specified by:

getBoolean in class ReflectiveDataProvider

Returns:

the boolean value or false.

getImage

public InputStream getImage(String fieldName)

Description copied from class: ReflectiveDataProvider

Get the image from the reflected delegate. If a method based on the given fieldName can be reflected, this will return the result of calling that method. NOTE: if fieldName contains period ('.') characters, then this is considered to indicate a nested structure. This method will recursively descend through the reflected delegate attempting to obtain data. If a method along the way returns null, then reflection cannot delve any deeper and null will be returned.

Specified by:

getImage in interface DataProvider

Specified by:

getImage in class ReflectiveDataProvider

Returns:

the reflected value or null.

getString

public String getString(String fieldName)

Description copied from class: ReflectiveDataProvider

Get the String from the reflected delegate. If a method based on the given fieldName can be reflected, this will return the result of calling that method. NOTE: if fieldName contains period ('.') characters, then this is considered to indicate a nested structure. This method will recursively descend through the reflected delegate attempting to obtain data.

public boolean hasBooleanKey(String fieldName)

Description copied from class: ReflectiveDataProvider

Determine if the boolean key has been set. If a method based on the given fieldName can be reflected, this will return true, otherwise false. NOTE: if fieldName contains period ('.') characters, then this is considered to indicate a nested structure. This method will recursively descend through the reflected delegate attempting to answer the question. If a method along the way returns null, then reflection cannot delve any deeper and false will be returned.

Specified by:

hasBooleanKey in interface DataProvider

Specified by:

hasBooleanKey in class ReflectiveDataProvider

Parameters:

fieldName - the name of the field to use for reflection
