Method Detail

getSQLiteDataType

public java.lang.String getSQLiteDataType()

Description copied from interface: Refractor

Defines the SQLite data type to be used when writing a value into the database. This is used to create the column definition.

Specified by:

getSQLiteDataType in interface Refractor<java.lang.Boolean>

Returns:

the SQLite data type string for this Java data type

getSQLiteDefaultValue

public java.lang.Boolean getSQLiteDefaultValue()

Defines the default value for Boolean types as false.

Specified by:

getSQLiteDefaultValue in interface Refractor<java.lang.Boolean>

Overrides:

getSQLiteDefaultValue in class Lens<java.lang.Boolean>

Returns:

false

toSQLiteString

public java.lang.String toSQLiteString(java.lang.Boolean o)

Description copied from interface: Refractor

Converts a Java thing's value into a string to be used in a SQLite query, for example, in a WHERE clause filter.

Specified by:

toSQLiteString in interface Refractor<java.lang.Boolean>

Overrides:

toSQLiteString in class Lens<java.lang.Boolean>

Parameters:

o - the Java thing to be converted

Returns:

a string serialization for use in an SQLite statement

getValueFrom

public java.lang.Boolean getValueFrom(SQLightable o,
                                      java.lang.reflect.Field fld)
                               throws java.lang.IllegalAccessException

Description copied from class: Lens

This implementation simply uses Field.get(java.lang.Object) and tries to cast it to the lens's template parameter type. Actual implementation classes should override this method if the data type is a primitive.

Specified by:

getValueFrom in interface Refractor<java.lang.Boolean>

Overrides:

getValueFrom in class Lens<java.lang.Boolean>

Parameters:

o - the object instance from which the value will be extracted

fld - the field from which the value will be extracted

Returns:

the value

Throws:

java.lang.IllegalAccessException

addToContentValues

public BooleanLens addToContentValues(android.content.ContentValues vals,
                                      java.lang.String sKey,
                                      java.lang.Boolean val)

Description copied from interface: Refractor

Determines the correct method in ContentValues to be used to add the specified value to a set of content values.

Specified by:

addToContentValues in interface Refractor<java.lang.Boolean>

Parameters:

vals - the set of content values

sKey - the content value key

val - the value to be stored

Returns:

(fluid)

addToBundle

public BooleanLens addToBundle(android.os.Bundle bndl,
                               java.lang.String sKey,
                               java.lang.Boolean val)

Description copied from interface: Refractor

Determines the correct method in Bundle to be used to add the specified value to an existing bundle.

Specified by:

addToBundle in interface Refractor<java.lang.Boolean>

Parameters:

bndl - the bundle

sKey - the field's key

val - the value to be stored

Returns:

(fluid)

Parameters:

crs - the cursor from which data should be fetched

sKey - the data column name

Returns:

the value from the cursor

fromBundle
