ComparisonFilter
abstract class ComparisonFilter extends SearchFilter (View source)
Base class for creating comparison filters, eg; greater than, less than, greater than or equal, etc
If you extend this abstract class, you must implement getOperator() and and getInverseOperator
getOperator() should return a string operator that will be applied to the filter, eg; if getOperator() returns "<" then this will be a LessThan filter
getInverseOperator() should return a string operator that evaluates the inverse of getOperator(), eg; if getOperator() returns "<", then the inverse should be ">=
Traits
A class that can be instantiated or replaced via DI
Provides extensions to this object to integrate it with standard config API methods.

Methods
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
Gets the uninherited value for the given config option
No description
Called by constructor to convert a string pathname into a well defined relationship sequence.
Parses the name for any aggregate functions and stores them in the $aggregate array
Set the root model class to be selected by this search query.
Set the current modifiers to apply to the filter
Accessor for the current modifiers to apply to the filter.
The full name passed to the constructor, including any (optional) relations in dot notation.
Return the value of the field as processed by the DBField class
Given an escaped HAVING clause, add it along with the appropriate GROUP BY clause
Applies a exclusion(inverse) filter to the query Handles SQL escaping for both numeric and string values
Determines case sensitivity based on getModifiers().
Find out whether the database is set to use case sensitive comparisons or not by default.
Details
static Injectable
create(mixed ...$args)
An implementation of the factory method, allows you to create an instance of a class
This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.
This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
static Config_ForClass
config()
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
mixed
uninherited(string $name)
Gets the uninherited value for the given config option
__construct(string $fullName = null, mixed $value = false, array $modifiers = [])
No description
protected
addRelation(string $name)
Called by constructor to convert a string pathname into a well defined relationship sequence.
protected
addAggregate(string $name)
Parses the name for any aggregate functions and stores them in the $aggregate array
setModel(string|DataObject $className)
Set the root model class to be selected by this search query.
setValue(string|array $value)
Set the current value(s) to be filtered on.
string|array
getValue()
Accessor for the current value to be filtered on.
setModifiers(array $modifiers)
Set the current modifiers to apply to the filter
array
getSupportedModifiers()
Gets supported modifiers for this filter
array
getModifiers()
Accessor for the current modifiers to apply to the filter.
string
getName()
The original name of the field.
setName(string $name)
No description
string
getFullName()
The full name passed to the constructor, including any (optional) relations in dot notation.
setFullName(string $name)
No description
string
getDbName()
Normalizes the field name to table mapping.
string
getDbFormattedValue()
Return the value of the field as processed by the DBField class
DataQuery
applyAggregate(DataQuery $query, string $having)
Given an escaped HAVING clause, add it along with the appropriate GROUP BY clause
bool
matches(mixed $objectValue)
Check whether this filter matches against a value.
protected DataQuery
applyOne(DataQuery $query)
Applies a comparison filter to the query Handles SQL escaping for both numeric and string values
protected DataQuery
applyMany(DataQuery $query)
Apply filter criteria to a SQL query with an array of values.
protected DataQuery
excludeOne(DataQuery $query)
Applies a exclusion(inverse) filter to the query Handles SQL escaping for both numeric and string values
protected DataQuery
excludeMany(DataQuery $query)
Exclude filter criteria from a SQL query with an array of values.
bool
isEmpty()
Determines if a field has a value, and that the filter should be applied.
Relies on the field being populated with setValue()
protected ?bool
getCaseSensitive()
Determines case sensitivity based on getModifiers().
protected bool|null
getCaseSensitiveByCollation()
Find out whether the database is set to use case sensitive comparisons or not by default.
Used for static comparisons in the matches() method.
abstract protected string
getOperator()
Should return an operator to be used for comparisons
abstract protected string
getInverseOperator()
Should return an inverse operator to be used for comparisons
protected bool
match(mixed $objectValue, mixed $filterValue)
