The abstract base class for Qore data types.
- Restrictions:
- Qore::PO_NO_REFLECTION
This class cannot be instantiated directly and also cannot be directly inherited by user-defined classes.
- Since
- Qore 0.9.0
◆ canConvertToScalar()
bool Qore::Reflection::Type::canConvertToScalar |
( |
| ) |
|
Returns True if values of this type can be converted to a scalar value.
- Code Flags:
- CONSTANT
- Example:
bool b = t.canConvertToScalar();
- Returns
- True if the output of the Type object passed as an argument is compatible with the return type if the current Type
◆ constructor()
Qore::Reflection::Type::constructor |
( |
| ) |
|
Throws an exception if called directly; this class can only be instantiated by builtin subclasses.
- Exceptions
-
TYPE-CONSTRUCTOR-ERROR | this exception is thrown if this class is constructed directly (also if directly inherited by user classes) |
◆ getDefaultValue()
auto Qore::Reflection::Type::getDefaultValue |
( |
| ) |
|
Returns the default value for the type or nothing if the type has no default value.
- Code Flags:
- CONSTANT
- Example:
auto v = t.getDefaultValue();
- Returns
- the default value for the type or nothing if the type has no default value
◆ getName()
string Qore::Reflection::Type::getName |
( |
| ) |
|
returns the type's name
- Code Flags:
- RET_VALUE_ONLY
- Example:
string name = t.getName();
- Returns
- the type's name
◆ getOrNothingType() [1/2]
Type Qore::Reflection::Type::getOrNothingType |
( |
| ) |
|
Returns the "or nothing" type for the current type; if the type is already an "or nothing" type (i.e. it already accepts nothing), then the same type is returned.
- Code Flags:
- CONSTANT
- Example:
auto v = t.getOrNothingType();
- Returns
- the "or nothing" type for the current type; if the type is already an "or nothing" type (i.e. it already accepts nothing), then the same type is returned
◆ getOrNothingType() [2/2]
static Type Qore::Reflection::Type::getOrNothingType |
( |
auto |
v | ) |
|
|
static |
Returns the "or nothing" type object for the value.
- Code Flags:
- CONSTANT
- Example:
Type t = Type::getOrNothingType(v);
- Returns
- the "or nothing" type object for the value
◆ getType()
static Type Qore::Reflection::Type::getType |
( |
auto |
v | ) |
|
|
static |
Returns the type object for the value.
- Code Flags:
- CONSTANT
- Example:
Type t = Type::getType(v);
- Parameters
-
v | the value to return the type object for |
- Returns
- the type object for the value
◆ hasDefaultValue()
bool Qore::Reflection::Type::hasDefaultValue |
( |
| ) |
|
Returns True if this type has a default value.
- Code Flags:
- CONSTANT
- Example:
bool b = t.canConvertToScalar();
- Returns
- True if this type has a default value
◆ isEqual()
bool Qore::Reflection::Type::isEqual |
( |
Type |
type | ) |
|
Returns True if the Type object passed as an argument is equal to the current object; False if not.
- Code Flags:
- CONSTANT
- Example:
- Parameters
-
type | the type to check with the current type for equality |
- Returns
- True if the Type object passed as an argument is equal to the current object; False if not
◆ isOutputCompatible()
bool Qore::Reflection::Type::isOutputCompatible |
( |
Type |
type | ) |
|
Returns True if the output of the Type object passed as an argument is compatible with the return type if the current Type.
- Code Flags:
- CONSTANT
- Example:
bool b = t1.isOutputCompatible(t2);
- Parameters
-
type | the type to check output value compatibility with the current type |
- Returns
- True if the output of the Type object passed as an argument is compatible with the return type if the current Type
